I am preparing to switch to Exchange 2007 CAS servers. I am required to allow secure POP and IMAP into the environment. I have GoDaddy UCC certificates with the proper names, the CN of each certificate is the FQDN of the server that it is installed on (I have been under the impression that this is the proper way to do the UCC certificates). Outlook Anywhere and OWA seem to be working fine, but when I access IMAP or POP I get a certificate warning saying the name doesn't match. The name it sees on the cert is the common name, but I am using mail.mydomain.com to access. I cannot change the common name of my certs now that I have bought them to mail.mydomain.com, but I didn't think I should have to. Does anyone know how I can fix this issue? I am assuming the outlook client can only see the common name on the Certificate? I tried doing a new CSR and just moving the mail.mydomain.com to the first name under domains, but it doesn't seem to matter how you order them. Any help would be greatly appreciated.
